  Newmarket Town, Soham Town Rangers, Cambridge City and Fulbourn Institute - teams for whom the pair played - will take part in a mini-tournament at the League Two club's stadium as one of a number of activities on the day.
  "I can't thank Lionel Messi and Arda Turan enough for donating their shirts and getting them to Cambridge," Whiter told BBC Look East.
  "We're going to auction them off and see what we can get."
  Jan Adamec, 40, from Haverhill, pleaded guilty to two charges of causing injury by dangerous driving and was jailed earlier this month for three years and four months.
  And Whiter, who has previously said he would like to compete at the 2020 Paralympics, spoke of the bond between him and Abbs following the incident.
  "He's a great friend. I've asked him to be one of the ushers at my wedding next year. He made that call that night to the paramedics to save my life," he added.
  "He saved my life and I can't repay him any more than with my friendship and support him through this time as well."
